Falsework required. No. A simple suspension bridge (also rope bridge, swing bridge (in New Zealand), suspended bridge, hanging bridge and catenary bridge) is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers.
Submerged floating tunnels can be anchored to the seafloor (left) or suspended from a pontoon (right) A submerged floating tunnel (SFT), also known as submerged floating tube bridge (SFTB), suspended tunnel, or Archimedes bridge, is a proposed design for a tunnel that floats in water, supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes' principle).
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. [5][6] Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
The first bridge to cross the lower Cooper River opened in 1929, eventually named the John P. Grace Memorial Bridge for former Charleston mayor John P. Grace, who spearheaded the project. The main span of the double cantilever truss bridge was the fifth-longest in the world at 1,050 feet (320 m) and soared 150 feet (46 m) above the river.
The Vasco da Gama Bridge (Portuguese: Ponte Vasco da Gama) is a cable-stayed bridge flanked by viaducts that spans the Tagus River in Parque das Nações in Lisbon, the capital of Portugal. It is the second longest bridge in Europe, after the Crimean Bridge, [8] and the longest one in the European Union. It was built to alleviate the congestion ...
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

The Humber Bridge is a 2.22 km (2,430 yd; 7,300 ft; 1.38 mi) single-span road suspension bridge near Kingston upon Hull, East Riding of Yorkshire, England. When it opened to traffic on 24 June 1981, it was the longest of its type in the world; the Akashi Kaikyō Bridge surpassed it in 1998, and is now the twelfth-longest.
A floating cable-stayed bridge is a type of cable-stayed bridge where the towers float on tension-leg submerged material, tethered to the seabed for buoyancy. No floating cable-stayed bridge has been made or planned yet, a floating suspension bridge has been planned in Norway. This bridge could be more stable horizontally across the bridge than ...
